A couple of weeks ago in a post on shooting brackets I referred to what I call the Michael Freeman manual method of shooting brackets. Michael describes it in his HDR book. I think this is important for people just starting out that want to learn how to be sure to capture the whole dynamic range in a scene with a set of brackets. I don't advocate processing the brackets with HDR. I think Exposure Fusion (EF) makes more sense for interiors. There's no special equipment required for this process and you don't have to have a DSLR that can shoot 5 or 7 or 9 brackets. You just do it manually.
Here's how it works: A key feature your DSLR requires is the ability to display a exposure histogram on the DSLR's LCD. Most modern DSLRs have this. The images to the right are from my LCD. The top one is the starting point (first bracket) and the bottom is from end point (last bracket). I'm using a 5DMKII with the brightness histogram on and in LiveView. Here are the steps:
I should remind you that while you are doing all this care should be taken not to move the camera in any way. What I do is use a remote shutter release in one hand so I don't have to touch the camera for releasing the shutter and roll the shutter thumb wheel with my other hand. I find this process is very reliable, fast and easy to use.
